Choose all the answers that apply MORE THAN ONE ANSWER. Salt is an ionic compound. It _____.
Anuta_ua [19.1K]

dissolves easily in water

has a high boiling point

has a high melting point

conducts electricity when melted

Explanation:

Salts are ionic compounds. Ionic compounds are formed when two atoms exchange their valence electrons. One atom gains and the other atom loses.

Generally, ionic compounds have the following properties:

  1. They are usually hard solids with high melting points or liquids with high boiling points.
  2. They are soluble in water and insoluble in non-polar solvents. This is conforms with the solubility rule that like dissolve like.
  3. In aqueous solution or molten form, ionic compounds conducts electricity.
  4. They take part in very fast chemical reactions.

If 1.332 mol of C4H10 are reacted with 6.504 mol of O2, how many mol of the excess reagent will remain unreacted? 2 C4H10 + 13 O
Luden [163]

Answer: The number of moles of excess reagent remain unreacted will be, 6.004 moles.

Explanation : Given,

Moles of C_4H_{10} = 1.332 mol

Mass of O_2 = 6.504 mol

First we have to calculate the limiting and excess reagent.

The balanced chemical equation is:  

C_4H_{10}+13O_2\rightarrow 10H_2O+8CO_2

From the balanced reaction we conclude that

As, 13 mole of O_2 react with 1 mole of C_4H_{10}

So, 6.504  moles of O_2 react with \frac{6.504}{13}=0.5003 moles of C_4H_{10}

From this we conclude that, C_4H_{10} is an excess reagent because the given moles are greater than the required moles and O_2 is a limiting reagent and it limits the formation of product.

Number of moles remain unreacted = 6.504 mol - 0.5003 mol = 6.004 mol

Therefore, the number of moles of excess reagent remain unreacted will be, 6.004 moles.

As k2o dissolves in water,the oxide ion reacts with water molecules to form hydroxide ions. write the molecular and net ionic eq
leva [86]

Solution:

The molecular equation is:

K_2O(aq.)+H_2O(l)\rightarrow 2KOH(aq.)

Now, the oxide ion reacts with water to produce hydroxide ions,

The ionic equation is:

2K^+(aq.)+O^{2-}(aq.)+H_2O(l)\rightarrow 2K^+(aq.)+2OH^-(aq.)

The 2K^+ ions are present on both the sides, so the net ionic equation becomes,

O^{2-}(aq.)+H_2O(l)\rightarrow 2OH^-(aq.)

Now, to determine acid and base, we will look at the definitions

Acid: It is defined as proton donor that is it donates H^+ ions.

Base: It is defined as proton acceptor that is it accepts H^+ ions.

In the ionic equation, water is donating H^+ ions to O^{2-} therefore it acts as an acid and oxide ion acts as a base.
